BARREL-REGOIL GUN.

T 0 all whom it may concern:

Be it known that I, Fnrrz FINGKH, residmg at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Barrel-Recoil Guns, (for which I have filed applicatlon in Germany, filed August 22nd, 1918,) of which the following is a specification.

This invention relates to barrel recoil guns and the object of the invention is to enable the guns of railway guns which are to be made or already existent naval guns to be used on a naval carriage or railway carriage without important alterations being made 1n the gun barrels and cradles.

This application is a division of my application Serial No. 408,376, patented May 24th, 1921, numbered 1,379,543.

The various features of the invention will be more particularly described with reference to the accompanying drawings in which Fig; 1 is a side elevation of a barrel recoil gun showing the parts pertaining to the present invention,

Fig. 2 is an end view of the structure illustrated in Fig. 1 looking from the left, and

Fig. 3 is a corresponding plan view.

In the drawings the reference character A indicates the gun barrel carried by a cradle F. The cradle F is provided with an arrangement for enabling a pair of trunnions G to be detachably fixed in either of two different positions on the cradle.

In order to accomplish this the cradle F has two pairs of oppositely located flat surfaces fand 7. The trunnions G have inte- Also formed integrally with the plates 9 and disposed opposite the trunnions are disc shaped projections g which are adapted to fit into the circular recesses f in the body of the cradle, thereby relieving the attachment screws of undue pressure.

Specification of Letters Patent. Patented Jan. 24, 1922.

Original application filed September 4, 1920, Serial No. 408,376. Divided and this application filed April Serial No. $64,682.

In assembling, the plates 9 are secured against theflat surfaces f or f by means of attachment screws or the like, with the disc shaped projections or members disposed within the circular recesses 7.

If the parts illustrated are to be used on a naval gun carriage, the trunnions g are attached to the front flat surfaces f of the cradle, whereas when the parts are to be used on a railway gun carriage the trunnions are fixed to the rear flat surfaces 7.

Having thus described my invention, what I claim is: V

1. A barrel recoil gun which comprises a gun barrel,a cradle therefor, a pair of trunnions, and means on said cradle cooperating with said trunnions enabling them to be detachably secured at different points on the cradle, as and for the purpose set forth.

2. A barrel recoilgun comprising a gun barrel, a cradle therefor, a pair of trunnions, said cradle being formed with pairs of oppositely disposed flattened surfaces and means for securing said trunnions to either pair of the flattened surfaces, as and for the purpose set forth.

3. A barrel recoil gun comprising a gun barrel, a cradle therefor, a pair of trunnions, said cradle being formed with pairs of oppositely disposed flattened faces, said flattened faces being provided with centrally disposed recesses, plates formed integrally to said trunnions, disc-shaped projections formed on said plates, said plates and projections cooperating with the flattened faces and recesses for removably securing the trunnions to the cradle.

Theforegoing specification signed at Essen, Germany, this 3rd day of March, 1921.
